To @ZZ whom t may concern: Y l

Be it known that I, BENJAMIN'F; KURTZ,

a citizen of the United -States,re'siding in Avalon, in the `county ofvAllegheny andl State of Pennsylvania', have invented cerf tain new anduseful Improvements in Brake-AdjustingzMechanism, of. which thefollowing is a specification. 1

adjusted so that the brake slioe Willbe main-V tained in its properposition when the brake is released without permanently.` bending the'spring to obtain such adjustment.

Referring to the drawing in which like reference characters refer tolike parts,` Fig. 1, is a sideelevational view of a portion of arailwaycar truck and brake mechanism having the invention embodiedtherein. Fig. 2, is anend elevational view of the saine taken in thedirection as indicated by the arrow A in Fig. 1. Y

Referring now in detail to the drawing the reference character-.1indicates a truck frame which may be of any suitable form orconstruction and having wheels 2- mounted therein in any preferredAmanner.V

The reference character 3 indicates a dead lever of the brake mechanism,the upper end portion of which is pivotally connected with the truckframe through the medium of aV pin f1. The' lower end portion of thislever is provided with abrake shoe head 5 Vsuch head being pivoted tothe lever through. the medium of a pin 6. The back portion of the headcomprises spaced portions 7 between which the lower portion of the lever3 ex-` tends and to which the lever is pivotally connected. Below thelower end of the lever 3 the head 5 is provided withV webs Sand 9 whichextend betweenV the spaced portions 1' and are preferably integraltherewith. These webs are spaced apart providing an opening 10 betweenthem. The' web 8 ad jacent the openin 10 is provided with an outwardlyprojecting lug 11 which is prefer-Y ably integral with the web. For thepurpose of holding the head 5 in its proper position so that the shoe 12secured thereto will notv drag on the wheelwhen the brake is released, aspring 13 is provided, the upper end portion 14 of which slidablyengages the through which l threaded This invention relates to railwaycar.

tlie lug 11 providing sufficient clearance be` tween the spring and thehead for proper Y adjustment.

It :will be noted that bythe use Vof thenut 19 the tension onthe springi" may be increasedor decreasedY as desired without permanently bendingthe spring as j Y has heretofore been the practice.

Having thus described the `invention what,

ters Patent is f 1. Ina brake mechanism, a brake lever, a brake shoeheadpivotally connected with desire to secure byk Let# said lever and vaspring mounted onfsaidj' head and engaging said lever and means in-1termediate the ends of said spring for .ad`V justing the tension of saidspring,

2. In a brake'inechanisni, a brake lever, a

brake shoe head pivotally connected with said lever, a spring mounted onsaidhead and engaging said lever' and screw means intermediate tlie endsofsaid'springfor adjusting the tension of said spring.

3. In a brake mechanism, a brake lever, a i

brake shoe'head pivotally connected with;

saidlever, a spring mounted in said head, a projection adapted to spacea portionrof said' spring away from said head andmeansadjacent saidprojection for adjusting the tension of said spring;

4c. In a brake mechanism, a brake lever, a brake shoe head pivotallyconnected with said lever, said head having spaced backV portions, websextending lbetween said spaced portions, a lug projectingfrom one ofsaid webs, a spring engaging said lever and lug and passing between saidwebsand means for adjusting the tension on said spring.

5. In a brake mechanism, a brake lever, a brake shoe liead connectedwith said lever, said head having spaced back portions, spaced websextending between said back portions, a spring engaging said lever andwebs, and means independent of said lever for adjusting the tensiononsaid spring;

6. In a brake mechanism, a brake lever, a brake shoe head, a springconnected with said head adapted to engage with said lever,

a lug on said head adapted to engage with said springend meansintermediate the ends 15 of said spring and between said levery and lugfor adjusting the tension on said spring. In testimony whereof l affixmy signature in the presence of two witnesses.
